1.环境准备

由于Geoserver自带的jetty版本不具备https模块，所以需要下载完整版本jetty。这里需要先查看本地geoserver对应的jetty版本，进入geoserver安装目录，执行如下命令。

java -jar start.jar --version

可以看到当前的jetty版本为9.4.48.v20220622,点击下载jetty。
jetty的zip包下包含如下文件：

我们需要将etc、lib、modules三个文件夹拷贝到geoserver对应的目录中。

2. 添加https模块

进入的geoserver的目录，当前目录包含start.jar文件，执行如下命令添加https模块

java -jar start.jar --add-to-start=ssl
java -jar start.jar --add-to-start=https

查看当前jetty加载模块：

java -jar start.jar --list-modules 

当然，我们也可以通过start.ini文件查看模块加载情况

# --------------------------------------- 
# Module: ssl
# Enables a TLS(SSL) Connector on the server.
# This may be used for HTTPS and/or HTTP2 by enabling
# the associated support modules.
# --------------------------------------- 
--module=ssl### TLS(SSL) Connector Configuration## Connector host/address to bind to
# jetty.ssl.host=0.0.0.0## Connector port to listen on
jetty.ssl.port=8081
...(此处省略N行)
# --------------------------------------- 
# Module: https
# Adds HTTPS protocol support to the TLS(SSL) Connector
# --------------------------------------- 
--module=https

此时，我们是通过https访问geoserver服务，默认端口为8443。只不过浏览器会有个安全的弹出框。

3. 配置证书

Jetty 需要使用的Key文件为keystore，而各大服务商申请的Key文件一般为pem等文件。因此我们需要对其做一下转换。

3.1 将pfx格式证书转换为jks格式证书

keytool -importkeystore -srckeystore surpass.pfx -destkeystore surpass.jks -srcstoretype 

3.2 将jks格式证书转换为p12格式证书

package com.surpass;import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.security.Key;
import java.security.KeyStore;
import java.security.cert.Certificate;
import java.util.Enumeration;/*** 证书转换* @author surpassliang* @date 2023/9/9 12:45*/
public class CertConvert {// 证书格式public static final String JKS = "JKS";public static final String PKCS12 = "PKCS12";/*** 证书和路径*/public static final String KEYSTORE_PASSWORD = "123456";/*** 证书别名*/public static final String CERT_ALIAS = "client";public static void main(String[] args) {if (args.length < 2) {System.out.println("参数不足，包含输入和输出参数");}//jksString inputKeystore = args[0];//p12String outputKeystore = args[1];try (FileInputStream fis = new FileInputStream(inputKeystore);FileOutputStream out = new FileOutputStream(outputKeystore)) {KeyStore inputKeyStore = KeyStore.getInstance(JKS);char[] nPassword = KEYSTORE_PASSWORD.toCharArray();inputKeyStore.load(fis, nPassword);KeyStore outputKeyStore = KeyStore.getInstance(PKCS12);outputKeyStore.load(null, KEYSTORE_PASSWORD.toCharArray());Enumeration<String> enumStars = inputKeyStore.aliases();while (enumStars.hasMoreElements()) {String keyAlias = enumStars.nextElement();if (inputKeyStore.isKeyEntry(keyAlias)) {Key key = inputKeyStore.getKey(keyAlias, nPassword);Certificate[] certChain = inputKeyStore.getCertificateChain(keyAlias);outputKeyStore.setKeyEntry(CERT_ALIAS, key, KEYSTORE_PASSWORD.toCharArray(), certChain);}}outputKeyStore.store(out, nPassword);System.out.println("转换完成....");} catch (Exception e) {System.out.println(e.getMessage());}}
}

3.3 将p12证书格式转换为 keystore文件格式

keytool -importkeystore -v -srckeystore surpass.p12 -srcstoretype pkcs12 -srcstorepass 123456 -destkeystore 你的证书.keystore -deststoretype jks -deststorepass 123456

3.4 将证书放到指定位置。

4. 配置证书

打开start.ini文件，找到如下位置，修改证书路径

jetty.keystore=etc/cert/ 你的证书.keystore
jetty.truststore=etc/cert/你的证书.keystore
jetty.keystore.password= 123456
jetty.keymanager.password= 123456
jetty.truststore.password= 123456

5.重启服务即可
